Move M8

Motion-Triggered Health & Wellness App

Personal Project 2024

Overview

Move M8 is a React Native mobile application designed to promote active lifestyles through intelligent, motion-triggered notifications. The app uses device sensors to detect periods of inactivity and sends contextual reminders to encourage movement and break sedentary behavior patterns.

Built with privacy-first principles, Move M8 stores all data locally on the device with no GPS tracking or external data collection. The app features customizable notification frequencies, multiple motivational tones, comprehensive streak tracking, and gamification elements to make healthy habits engaging and sustainable.
